Value Collection R52000825 No. 4 Sheet Metal Screw

Product Description

The VALUE COLLECTION R52000825 is a No. 4 sheet metal screw with a hex washer head and slotted drive, designed for fastening light-gauge sheet metal and similar thin materials. The screw measures 0.375 inches in length under the head and features a Type AB point for self-starting in pre-pierced or drilled sheet metal applications. Constructed from Grade 1016-1024 steel with a zinc-plated finish, it provides corrosion resistance suitable for general indoor and light industrial use. This fastener is sold in multiples of 100 per order.

This screw is used in residential and light commercial applications wherever sheet metal panels, brackets, HVAC ductwork components, electrical enclosures, or similar thin-gauge assemblies require a reliable threaded fastener. The hex washer head allows for socket or nut driver installation, while the slotted drive provides a secondary drive option. The Type AB thread form engages quickly in thin material without requiring a tapped hole, making it a common choice for production assembly and field service work across HVAC, electrical, and sheet metal trades.

Key Features

• No. 4 thread size for light-gauge sheet metal fastening
• 0.375 inch length under head suits thin-material stacking
• Type AB point self-starts in pre-pierced or drilled holes without tapping
• Hex washer head accepts nut driver or socket for fast installation
• Zinc-plated Grade 1016-1024 steel meets AISI, ASME, and SAE standards
• Slotted drive provides backup drive option in tight spaces

Compatibility

Designed as a standard No. 4 Type AB sheet metal screw suitable for use in light-gauge steel panels, sheet metal enclosures, and similar thin-material assemblies where ASME B18.6.4 and SAE J933 fastener standards apply.

Installation Notes

Installation is performed by sheet metal workers, HVAC technicians, and electricians using a nut driver, slotted screwdriver, or hex socket. Pre-pierce or pre-drill the base material per the fastener manufacturer recommendations for the gauge being fastened. Do not overdrive — hex washer head fasteners can strip thin material if torque is not controlled. Follow applicable codes such as SMACNA standards for duct fastening or NEC requirements for electrical enclosure work.
